| * This is an EJB 3 style pojo stateful session bean |
| * Every stateful session bean implementation must be annotated |
| * using the annotation @Stateful |
| * This EJB has 2 business interfaces: CounterRemote, a remote business |
| * interface, and CounterLocal, a local business interface |
| * |
| * Per EJB3 rules when the @Remote or @Local annotation isn't present |
| * in the bean class (this class), all interfaces are considered |
| * local unless explicitly annotated otherwise. If you look |
| * in the CounterRemote interface, you'll notice it uses the @Remote |
| * annotation while the CounterLocal interface is not annotated relying |
| * on the EJB3 default rules to make it a local interface. |
